Title: Magnetic disk drive
Inventor: TANAKA MASAYA
IPC: G11B5/09
Filed: 1990-11-13
Abstract: PURPOSE:To improve the recording density without changing a magnetic head, a magnetic disk or the like by making the inter-code interference at a reproducing clock point zero with use of an equalizer obtaining the Nyquist waveform. CONSTITUTION:In reading data, a magnetic head converts the magnetic pattern on the disk surface to electric signals which are then amplified by a preamplifier 1. The output of the amplifier 1 is input to an AGC amplifier 2, so that the amplitude of the output is made constant there. The output from the AGC amplifier 2 is input to an equalizer 5. The output of the equalizer 5 is added to an output which is delayed by one clock in a delay circuit 6, and input to a maximum likelihood decoder 7, thereby to obtain the output data. The adding operation of the output obtained through equalization of the waveform to the output is expressed, in terms of partial response, by 1+D. And, the operation from recording to reproduction is expressed by 1-D. Therefore, the 1+D operation in the reproducing system is expressed by (1-D).(1+D)=1-D<2>. This apparatus eventually uses a class IV partial response method effective to achieve magnetic recording in a higher band with higher density.

Abstract: PURPOSE:To obtain a resin emulsion having excellent dispersion stability and uniform particle size of the resin particles, by polymerizing an alkyl (meth) acrylate up to a specific polymerization ratio, adding an unsaturated carboxylic acid and a copolymerizable monomer to the system and continuing the polymerization. CONSTITUTION:An alkyl (meth)acrylate having 1-4C alkyl group is polymerized in an aqueous medium in the presence of a redox polymerization initiator until the polymerization ratio reaches >=60%, when the polymerization system is added with an unsaturated carboxylic acid [e.g., (meth)acrylic acid] and a copolymerizable monomer [e.g., alkyl (meth)acrylate, styrenes or fluoroalkyl (meth)acrylate] and the polymerization reaction is continued. The redox polymerization initiator is preferably composed of 0.5-20wt.% [based on 100 pts.wt. of the alkyl (meth)acrylate] of a peroxide-type polymerization initiator and 1-100mol% (based on the initiator) of a reducing agent (e.g., potassium thiosulfate).

Title: Pll synthesizer
Inventor: SAKAMOTO MASARU
IPC: H03L7/10
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To obtain a PLL synthesizer where a voltage controlled oscillator is locked up at high speed after application of power so as to sufficiently meet requirements of high speed lockup time at starting with respect to a communication system desiring immediate communication start after the start. SOLUTION: The PLL synthesizer is provided with a voltage controlled oscillator 11, a variable frequency divider 12, a reference oscillator 15, a phase comparator 3 that outputs a difference voltage VPD in response to a frequency difference between a frequency division signal and a reference frequency signal, a loop filter 14, a voltage regulator 17 that outputs an initial setting voltage VR with a voltage nearly equal to a DC control voltage VC at which an output frequency signal with a target frequency is obtained, and with a switch 18 that selects the initial setting voltage VR as the DC control voltage VC at application of power to the synthesizer and selects the oscillated frequency control voltage after a prescribed time T.  Since a difference between the output frequency at the start of lock up and the target output frequency is small, a time required for convergence is enough small and the lockup time at start is quickened.

Title: Accumulator
Inventor: KONISHI SEIJI
IPC: F25B43/00
Filed: 1990-11-09
Abstract: PURPOSE:To prevent the deformation of one filter, and to previously prevent the seizure of sliding-parts such as cylinders in a compressor, by a method wherein a by-pass with a pressure-reducing function is provided between the primary side of the filter and the secondary side thereof, and the other filter is provided at the opening part on the secondary side of the by-pass. CONSTITUTION:When a large amount of a liquid refrigerant suddenly flows in an accumulator main body 1 through an inlet pipe 2, the liquid refrigerant collected on the primary side of a filter 6 is quickly led to a by-pass 8. While the liquid refrigerant is passing the bypass 8, the pressure of the liquid refrigerant is reduced and is gasified, following which this gaseous refrigerant is supplied to the second side of the filter 6 and is returned to a compressor. Since the liquid refrigerant on the primary side is supplied to the secondary side through the bypass 8 by being gasified even if all the surface of the filter 6 is covered with the liquid refrigerant, a pressure difference between the primary side and the secondary side is prevented from increasing, and a sufficient amount of the gaseous refrigerant, with which sliding parts such as cylinders do not seize, can be supplied to the compressor.

IPC: G03B27/20
Filed: 1988-12-03
Abstract: PURPOSE:To integrate stripping work and contact printing work by adding a write table function to a contact printer performing the contact printing of film. CONSTITUTION:To use the device for a contact printer, a write table frame 2 is elevated, and a write table light source 10 is moved in the retreat position behind the frame 1.

Light emitted from the write table light source 10 passes through the transparent plate 7, and illuminates a frosted glass 5 from below, thereby constituting the write table suitable for the stripping work. Consequently, an operator can carry out any work, seating himself in a home position before the device.

Title: Manufacture of substrate for cathode of lead-acid battery
Inventor: ABE HIDETOSHI
IPC: H01M4/68
Filed: 1988-12-03
Abstract: PURPOSE:To lengthen the life of a battery by forming a tin film on the surface of a substrate made of lead or a lead alloy and by heating it. CONSTITUTION:A tin film is formed on the surface of a substrate made of lead or a lead alloy, then heated. The surface layer of the tin film is oxidized to SnO2 and its inside stays is the tin layer. Part of the tin layer penetrates into the substrate and forms an alloy with lead on the interface to form a strong composite film united with the substrate. When the substrate obtained is used for a positive plate, formation of high impedance layer such as irreversible PbO2 layer is prevented, chargeability after long hours standing is increased, and charging time reaching a specified capacity is shortened. Since tin and lead are strongly bound to the substrate, separation is prevented and the life is lengthened.
